Embodiment
Here the MCCH that embodiment relates to for distributed MCE upgrades the synchronous of signaling.
Fig. 4 shows the communication network 400 that wherein can realize embodiment here.Communication network 400 is applicable to the wireless access technology of such as LTE.
Wireless communication networks 400 comprises for the first community 403a provides an eNB 401a of service, and be can be present in the entity of the subscriber equipment 405 in the first community 403a at the enterprising Serial Communication of radio bearer.MBMS and/or eMBMS supported by subscriber equipment 405.One eNB401a comprises MCE (not shown).
Wireless communication networks 400 comprises for the second community 403b provides the 2nd eNB 401b of service, and be can be present in the unit of the subscriber equipment 405 in the second community 403b at the enterprising Serial Communication of radio bearer.2nd eNB 401b comprises MCE (not shown).
When subscriber equipment 405 such as moves from the first community 403a to the second community 403b, subscriber equipment 405 by certain in the overlapping region between the first community 403a and the second community 403b a bit.In this overlapping region, subscriber equipment 405 can communicate with both the 2nd eNB 401b with an eNB 401a.
Subscriber equipment 405 can be mobile or fixing any equipment that can communicate over the wireless channel in communication network, such as be not limited to the consumer electronics product of such as mobile phone, smart phone, transducer, gauge, vehicle, household electrical appliance, medicine equipment, multi-media player, camera or any type, such as, but be not limited to TV, radio, lighting installation, flat computer, laptop computer or PC.Subscriber equipment 405 is called as UE in some drawings.
MBSFN region 407 comprises the first community 403a and the second community 403b.
Communication network 400 also comprises the MME 410 sending chain of command signaling to an eNB 401a and the 2nd eNB 401b.Chain of command signaling can be such as MBMS session start request, and it comprises the MBMS data delivery time.MBMS GW 415 performs MBMS session control signaling (session start/stopping) via MME 410 to an eNB401a and the 2nd eNB 403b.
The method of the processing configuration information according to some embodiments is described now with reference to the signaling diagram shown in Fig. 5.Below, no matter eNB is an eNB or the 2nd eNB, uses Reference numeral 401 when referring to the eNB on ordinary meaning.The method comprises the following steps, and these steps also can perform according to another the suitable order being different from order described below.
step 501
MME 410 sends MBMS session start request to eNB 401.MBMS session start request comprises the attribute of MBMS session, such as parametric t imeOfMbmsDataTransfer.Session start is the triggering of the bearing resource foundation that MBMS data transmits.MBMS session start request can be eMBMS session start request.
step 502
When eNB 401 receives the MBMS session start request from MME 410, eNB401 calculates the very first time starting MBMS session based on the MBMS session start request received.The very first time is MCCH update time.
Before the real data transmission of MBMS session starts, need to send MCCH update signal to subscriber equipment 405.But, after the real data of MBMS session transmits stopping, needing to send MCCH update signal to subscriber equipment.
Whether the mode calculating MCCH update time depends on parametric t imeOfMbmsDataTransfer and is included in MBMS session start request, or whether alternatively uses current time (that is, timeOfMbmsDataTransfer is unavailable).
In order to calculate MCCH update time (and the 2nd MCCH update time in step 503), need to revise period count to MCCH.In order to the concept of MCCH update time can be used, segment number when needing to revise MCCH in eNB 401.Therefore, McchModificationPeriodStartTime is needed.MCCH revises the border that period delimiting period occurs, i.e. the radio frame of its SFN mod mcchModificationPeriod=0, wherein SFN is the abbreviation of System Frame Number.MchhModifcationPeriodStartTime can be configured to identical with the SFN time started.For the node that global positioning system (GPS) is synchronous, when GPS starts, SFN starts (being 0).In this example, gps time starts when 1980-01-0600.00.00 (being 0), and the midnight namely between 5 days and 6 days January in 1980 starts.So can be numbered the McchModificationPeriod started at McchModificationPeriodStartTime place.
When the MBMS session start request received in step 501 comprises parametric t imeOfMbmsDataTransfer, calculate the MCCH update time starting MBMS session by using timeOfMbmsDataTransfer, see table 1.This is converted into the time (if they are different) based on the identical clock used from mcchMoficationPeriodStartTime.The scope of McchUpdateTime is 0...255.MCCH upgrades signaling at least one MCCH before Mbms user data starts to send and revises period transmission.
Table 1 is based on MCCH update time of timeOfMbmsDataTransfer
In table 2 below, scene there is not timeOfMbmsDataTransfer in MBMS session start request, or wherein timeOfMbmsDataTransfer passes by.In this scenario, use current time as an alternative, to calculate MCCH update time.MBMS session started as early as possible in the MCCH amendment period that the next one is available.
Table 2 is based on MCCH update time of current time
step 503
ENB 401 calculates for removing or the second time of stopping MBMS conversation.The calculating of the second time is based on the very first time calculated in step 502 and complete based on timeOfMbmsDataStop (if it is available).If timeOfMbmsDataStop is unavailable, alternatively current time can be used.Second time was MCCH update time.MBMS session can be eMBMS session.It is the point not having data to send within a period of time that MBMS session stops.This is converted into the time (if they are different) based on the identical clock used from mcchMoficationPeriodStartTime.The scope of McchUpdateTime is 0...255.
When considering MBMS session life time, according to above table 1 or table 2, the first session start (its be called as a MCCH update time) is based on TimeOfMbmsDataTransfer.Then need to stop session.This is called as MCCH update time.Session can receive MBMS session at eNB 401 and stop stopping during request.Can calculate for the 2nd MCCH update time by different modes, such as, in table 3,4 and 5 illustrated.
Parametric t imeOfMbmsDataStop can be included in MBMS session to be stopped in request.In one embodiment, in table 3, calculated for the 2nd MCCH update time by operation parameter timeofMbmsDataStop.Term " normally " here means: stop receiving timeOfMbmsDataStop in request in MBMS session, and it does not indicate the time of having pass by.When using timeofMbmsDataStop, at least one MCCH amendment period of MCCH renewal signaling after Mbms user data stops sending sends.
Table 3 is based on the 2nd MCCH update time of timeOfMbmsDataStop
In another embodiment, in table 4, calculated for the 2nd MCCH update time by using current time.This refers to the abnormal conditions that MBMS session stops, and wherein extremely refers to stop parametric t imeOfMbmsDataStop in request unavailable in MBMS session.ENB 401 misses MBMS session and stops request, and removes resource after performing examination (audit) function.MBMS session stopped as early as possible in the MCCH amendment period that the next one is available.
Table 4 is based on the 2nd MCCH update time of current time
In another embodiment, MBMS session can be stopped by session persistence time-out, see with following table 5.Then the 2nd MCCH update time will based on MBMS session persistence and timeOfMbmsDataTransfer.MCCH upgrades signaling at least one MCCH after MBMS session persistence time-out and revises period transmission.
The two MCCH update time of table 5 when MBMS session persistence time-out
step 504
ENB 401 periodically sends configuration information to subscriber equipment 405 from the very first time.Configuration information is MBSFN area configurations information.Configuration information is carried by MCCH.Configuration information indicates ongoing MBMS session or eMBMS session, and (accordingly) radio resource configuration.The scheduling (i.e. MBSFNAreaConfiguration message) of MCCH information is based on the amendment period configured and repetition interval.Within the amendment period, same MCCH information can be sent out repeatedly, and this is based on configured repetition interval.
step 505
The very first time place calculated in step 502, namely when transmitting MBMS data to subscriber equipment 405, MBMS session start.MBMS session can be such as TV programme.MBMS session can be eMBMS session.
step 506
ENB 401 checks whether MBMS session is last MBMS session.
step 507
If MBMS session is last session, then eNB 401 stops periodically sending configuration information to subscriber equipment, and removes all MBMS resources.Stop locating occurring in the second time calculated in step 503.
step 508
This step alternative steps 507 and performing.If MBMS session is not last session, then eNB 401 sends the configuration information upgraded to subscriber equipment 405.The configuration information upgraded is the MBSFN area configurations information upgraded.Such as because network has changed configuration information at least partially, so upgrade configuration information.
Fig. 6 shows eMBMS notice.MCCH information can only change at the boundary of amendment period.When MCCH information will change, by sending change during a MCCH amendment period n 602, eNB 401 notifies that 601 notify described change to subscriber equipment 405.This step is not shown in Figure 5.Revise in period n+1603 at next MCCH, eNB 401 sends the MCCH information 604 of new/renewal.New/MCCH information 604 of upgrading is identical with MBSFN area configurations information.The cyclical transmission of configuration is based on MCCH repetition interval 605.As mentioned in early time, MBSFN region 407 comprises multiple communities of the transmission simultaneously performing same waveform.MBSFN transmission from the multiple communities 403 in MBSFN region 407 is considered as single transmission by subscriber equipment 405.When by MME 410 during MBMS session, all communities 403 (in all eNB 401) in identical MBSFN region 407 need to revise the period at identical MCCH and upgrade this information.Otherwise, will disturb.As described in step 507, identical principle will be applicable to MBMS session and stop.
Like this, MCCH is incorporated in all eNB 401 update time.MCCH update time based on MBMS data transmit time/time of stopping of MBMS data or calculate based on current time.By using identical method in all eNB 401, MCCH will be realized and upgrade synchronization.
Fig. 7 shows the MCCH update time of normal MBMS session start request and MBMS session stopping request (namely when parameter TimeOfMbmsDataTransfer and timeOfMbmsDataStop is available).MCCH update time 701 is shown in the centre of Fig. 7.In MCCH update time 701, MCCH update time of Mbms session start 703 is 255.The somewhere of TimeOfMbmsDataTransfer 705 in MCCHUpdateTime=0 occurs.The somewhere of TimeOfMbmsDataStop 707 in MCCHUpdateTime=3, and MBMS session stops Mcch update time of 710 to be at MCCHUpdateTime=4 place.
Now said method is described the angle from eNB 401.Fig. 8 is the flow chart of this method for the treatment of configuration information described in eNB 401.As mentioned above, configuration information is MBSFN area configurations information.In certain embodiments, eNB 401 comprises MCE, and MCE performs following method.The method comprises the additional step that will be performed by eNB 401, and this step can perform according to any suitable order:
